What I have found is that you need to create your own opportunities. For example, in my high school where I work as a French teacher, I proposed a one-semester mindfulness course for my students. I was fortunate that my admin team was on board with the idea (having a school climate/student survey demonstrated the need quickly however) and the course took off so quickly that I was able to implement a second semester mindfulness course. I am now teaching four sections of mindfulness and 3 sections of French (we have another French teacher who picks up the other sections).
If you are interested in going the education route, I strongly suggest getting buy-in from admins and teachers first by offering a before or after school workshop or several weekly sessions. Once a few educators get on board, you can offer courses to them for a fee (speak with the HR department to see if they would be willing to pick up half of the cost - it will help reduce stress in their employees!) and then perhaps then propose a course for the students.
Just a few thoughts. :)
